What's included
A complete commercial window cleaning service
Dirty windows affect how clients, customers, and staff perceive your premises. Our commercial window cleaning service covers everything — from ground-floor shopfronts to upper-floor office glazing — using pure water reach-and-wash systems that leave a streak-free, spot-free finish without ladders or scaffolding up to 4 storeys.

Pure water reach-and-wash system
We use a water-fed pole system with purified water — no detergents, no residue, no streaks. The pure water attracts and holds dirt particles as it dries, leaving glass cleaner for longer than traditional methods. Safe for UPVC frames, aluminium, and all commercial glazing types.
Flexible scheduling
Window cleaning can be scheduled monthly, fortnightly, or quarterly depending on your premises and footfall. We work around your business hours — early morning, evenings, or weekends — so there's no disruption to your operations.

Common questions
Window cleaning FAQs
Do you clean windows internally and externally?
Yes. We provide both internal and external commercial window cleaning. Most clients opt for a combined service — external cleaned by reach-and-wash pole system, internal cleaned by hand with streak-free solution.
Can you clean high-level or difficult-access windows?
Yes. We use water-fed pole (reach-and-wash) systems that can reach up to 4 storeys without ladders or scaffolding. For higher levels we can arrange specialist access equipment.
How often should commercial windows be cleaned?
Most commercial premises benefit from monthly external window cleaning. High-footfall retail and hospitality venues often require fortnightly cleans. Internal window cleaning is typically quarterly for offices, or more frequently for client-facing premises.
Is your window cleaning service available alongside regular cleaning?
Yes. Window cleaning can be added to any existing CQD cleaning subscription as a scheduled add-on, or booked as a standalone service. Many clients combine daily office cleaning with monthly window cleaning under a single contract.
